Patent CA-2383529-A1 (CA)
Inventor: ELLEMOR JOHN WARWICK
IPC: A63B53/04
Filed: 2000-08-18
Abstract: A golf club, namely a driver, includes a flowing moving part within the head such as mercury or a flowable solid in an inclined U shaped hollow passage (11). The moving part (12) remains captive at the rear of the head during the downswing on an axis defined by the direction of travel and the centre of mass. A golf ball impacting the head away from this axis e.g. at the toe (17) causes the head to rotate and subsequently causing the flowing moving part (18) and hence the centre of mass to move to behind the point of impact i.e. the toe, thus reducing head rotation and increasing the sweet spot.

Patent CA-2395799-A1 (CA)
Title: Method and apparatus for controlling temperature of cooling air for glass manufacturing machine
Inventor: MACE DOUGLAS K
IPC: G05D23/00
Filed: 2002-07-26
Abstract: The temperature of cooling air to a manifold for distribution to molds of a glass manufacturing machine is controlled by passing untreated air through an indirect heat exchanger in indirect heat exchange relationship with water flowing through a coil in the indirect heat exchanger before treated air from the indirect heat exchanger is passed through a blower for distribution to the manifold. Water for treating the air flowing through the indirect heat exchanger is pumped through the coil from a water cooling tower that is used in a glass manufacturing plant, either at a first temperature from a first outlet of the water cooling tower or at a second temperature from a second outlet of a water cooling tower, or a mixture of water from the first outlet and the second outlet. In a first embodiment, water from the first outlet and water from the second outlet pass through a temperature controlled three-way mixing valve before delivery to a pump for delivery to the indirect heat exchanger. In a second embodiment, water from a first outlet is delivered to a pump and then to a temperature control three-way valve for delivery to khe indirect heat exchanger or for return to a location upstream of the pump. In the latter embodiment, air from the blower is also caused to flow through a second indirect heat exchanger before delivery to the manifold, and its temperature is altered in the second indirect heat exchanger in indirect heat exchange relationship with water flowing through a coil in a second indirect heat exchanger. In this embodiment, water flows from the water cooling tower to the coil of the second indirect heat exchanger, and a temperature controlled two-way valve is placed in a line between the water cooling tower and the second indirect heat exchanger to control the rate of water flowing through the second indirect heat exchanger.

Title: A method of cleaning crankcase gas
Inventor: FRANZEN PETER
IPC: F01M13/04
Filed: 2000-10-27
Abstract: In connection with cleaning of crankcase gas from particles suspended therein and being heavier than the gas, the gas is caused to rotate in a chamber delimited in a stationary housing, so that the particles by centrifugal force are separated from the gas and are thrown towards a stationary housing. The rotation of the gas is accomplished by means of a rotor, which includes a stack of conical separation discs arranged coaxially with each other and concentrically with the rotational axis of the rotor. The gas to be cleaned is caused to flow through interspaces between the separation discs, while they are rotating, the particles by the centrifugal force being brought into contact with the insides of the separation discs.
